摘要
We report a novel multilayered organic-inorganic hybrid material, beta ''-(BEDT-TTF)(2)[(H2O)-(NH4)(2)Rh(C2O4)(3)].18-crown-6. This is the first molecular superconductor to have a superlattice with layers of both BEDT-TTF and 18-crown-6 and also the first with the anion tris(oxalato)rhodate. This is the 2D superconductor with the widest gap between conducting layers, where only a single donor packing motif is observed (beta ''). The strong 2D nature of this system strongly suggests that the superconducting transition is a Kosterlitz-Thouless transition. A superconducting T-c of 2.7 K at ambient pressure was found by transport measurements and 2.5 K by magnetic susceptibility measurements.
